    Abstract: The present technique relates to a processing device and a processing method for realizing sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the processing device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). With the microphone being located in the space sealed off from outside, emitted speech voice that propagates through the ear canal of the wearer is collected. In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies Further, an equalizing process for reducing muffled sound that is generated when sound is collected through the ear canal is performed on the sound collection signal.

    Abstract: Provided is a headphone driver including a yoke that has a bottom surface and an erected surface that is erected in a perpendicular direction with respect to the bottom surface, and that is formed using a magnetic material, and a bonded magnet unit consisting of a bonded magnet that is provided on the bottom surface of the yoke. The magnetic flux of the bonded magnet unit is concentrated on the side surface of the bonded magnet unit facing the erected surface of the yoke.

    Abstract: According to the present disclosure, a sound output device includes: a sound acquisition part configured to acquire sound to be output to the other end of a sound guide part, one end of which is arranged near an entrance of an ear canal of a listener, the sound guide part having a hollow structure; and a head-related transfer function adjustment part configured to adjust a head-related transfer function of sound captured by the sound guide part. Since the head-related transfer function adjustment part adjusts the head-related transfer function of sound captured by the sound guide part, it is possible to listen to both ambient sound and sound provided from a sound output device such that the listener does not feel strangeness even in the state in which the listener is wearing the sound output device.
